On the campaign trail, Trump promised to tackle a $1 trillion infrastructure bill within his first 100 days in office, but the issue slipped to the back burner amid other GOP priorities like health care and tax reform last year.

But Trump hopes to put infrastructure back at the top of his agenda in the New Year.

The White House is supposed to unveil “detailed legislative principles” later this month outlining Trump’s infrastructure vision, which lawmakers will use as a blueprint to craft a bill while Trump works to sell the idea to the public, state and local officials, and members of Congress.

The issue is also likely to be pitched during Trump’s inaugural State of the Union address on Jan. 30.

But there have been mixed messages from Republican leaders about whether infrastructure will be a top goal for the GOP this year.
